Title: Innovations by Sih-Hao Chiang in Terephthalic Acid Manufacturing

Introduction

Sih-Hao Chiang is a notable inventor based in Taoyuan, Taiwan. He has made significant contributions to the field of chemical manufacturing, particularly in the production of terephthalic acid. With a total of 2 patents to his name, Chiang's work is recognized for its innovative approaches and practical applications.

Latest Patents

Chiang's latest patents include a method for manufacturing terephthalic acid. This method involves several steps, starting with the provision of a titrant receptor solution, which is primarily water. He then adds a disodium terephthalate aqueous solution and an acid titrant to this solution, resulting in the formation of terephthalic acid crystals and an end-point solution. The process concludes with the separation of the terephthalic acid crystals from the end-point solution.

Another significant patent by Chiang is a method for manufacturing terephthalic acid that includes a series of operations. This process begins with providing a raw material, specifically polyethylene terephthalate. A depolymerization reaction is performed on this raw material to create a depolymerization product, which consists of disodium terephthalate. Following this, a decolorization process is conducted on the disodium terephthalate to yield decolorized disodium terephthalate and precipitated sludge. The final steps involve separating the decolorized disodium terephthalate from the sludge and forming terephthalic acid from the decolorized product.
